Most of government meddling in markets falls into three categories: 1) Redistibution, 2) Regulation, and 3) Borrowing.

1. Redistribution: They take your money and give it to someone else.
2. Regulation: They tell you how you must spend you own money.
3. Borrowing: They either crowd out valid investments, or they use it as excuse for monetary expansion.

I will focus mostly on these topics, but everything connects.
